WebThe critical section for the two way shear or punching shear occurs at a distance of d/2 from the face of the column (Fig. 9), where a and b are the dimensions of the column. Hence, punching area of footing = (a + d) 2 = (0.30 + 0.376) 2 = 0.457 m 2 where a = b = side of column. Punching shear force = Factored load - (Factored average pressure ...
